Bruce,
You don't have to have any axes that are "offending"! You can control the
axes with the plot options Axes, AxesOrigin and AxesStyle. Look these up in
Help. You may also wish to use Frame. You can have a Frame and Axes inside
the Frame. Here is an example.
Plot[10 - (x - 7)^2, {x, 0, 14},
Frame -> True,
AxesOrigin -> {7, 0},
AxesStyle -> {{Automatic}, {AbsoluteDashing[{5}]}}];
Plot options are very important for making a graph have the overall look
that you desire.

When 2D-plotted axes don't intersect at the origin, I want to dash the
offending
one, e.g., dash the horizontal if it's y == 7.
How can this be done automatically for all 2D-plots?
Thanks.
Bruce
